Help with cracking a zip Password
#1
Hi there,

I'm trying to mess around with hashcat... but i don't really get it Undecided

I'm trying a simple example:
I create zip file with a 10 character Password, containing hex and + / -

like f7ab-f1a+4 

Then i extracted the hashes
zip2john test.zip > test.hash

i tried to mess around with the examples from the wiki, but i can't get anything to work...

hashcat64 -a 3 -1 abcdef1234567890+- ?1?1?1?1?1?1?1?1?1?1 test.hash

hashcat (v4.0.1) starting...
* Device #1: WARNING! Kernel exec timeout is not disabled.
             This may cause "CL_OUT_OF_RESOURCES" or related errors.
             To disable the timeout, see: https://hashcat.net/q/timeoutpatch

You'll need a -m parameter as well.
